Triosephosphate Isomerase Deficiency is a rare genetic disorder that affects the metabolism of carbohydrates in the body. It is not contagious and cannot be transmitted from person to person. This condition is inherited in an autosomal recessive manner, meaning that both parents must carry a mutated gene for their child to be affected. Triosephosphate Isomerase Deficiency is a result of a specific genetic mutation and does not spread through contact or exposure.
